# NTSB LAX02LA206: Beech BE76, N6627U, Prescott, AZ, June 13, 2002 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: June 13, 2002, 11:43 local (18:43 UTC) - Place: Prescott, AZ - Coordinates: 34.657501, -112.421669 - Nearby events: https://openairdocs.org/map.md?lat=34.6575&lon=-112.4217&mi=10 - Phase of flight: [Takeoff](https://openairdocs.org/ntsb-phases/300) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report September 30, 2003 - Report: Approved by Office Director - Parties: FEDERAL AVIATION ADMINISTRATION - NTSB case key (mKey): 55002 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=LAX02LA206 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/55002/pdf - NTSB docket: https://data.ntsb.gov/Docket?ProjectID=55002 - Page: https://openairdocs.org/ntsb/LAX02LA206 ## Probable cause The student pilot's decision to abort the takeoff with insufficient runway remaining, resulting in a runway overrun and collision with a berm. A factor was the cabin door opening during the takeoff roll. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Overrun, takeoff - roll/run - door - open (contributing factor) - aborted takeoff - attempted, dual student - remedial action - initiated, dual student - all available runway - not used, dual student (cause) - On ground/water encounter with terrain/water, takeoff - aborted - terrain condition - berm ## Analysis During an aborted takeoff due to an open door, the airplane impacted a dirt berm at the departure end of the runway. While conducting touch-and-go takeoffs and landings, the student pilot's door popped open. The student retarded the throttles and applied brakes. The CFI assessed the situation, and decided that they could not safely continue the takeoff due to low airspeed and no remaining runway. She then assisted the student with directional control and braking action. The airplane departed the runway and collided with a dirt berm. There were no discrepancies noted with the airplane by the CFI or student pilot. ## Factual narrative On June 13, 2002, about 1143 mountain standard time, a Beech BE76, N6627U, impacted a dirt berm at the departure end of runway 21R after aborting a touch-and-go takeoff at the Ernest A. Love Field Airport (PRC), Prescott, Arizona. The airplane, operated by Embry-Riddle Aeronautical University as an instructional flight under the provisions of 14 CFR Part 91, sustained substantial damage. The certified flight instructor (CFI) and private pilot were not injured. Visual meteorological conditions prevailed for the local area instructional flight, and a company visual flight rules (VFR) flight plan had been filed. The flight originated at PRC about 1000 the morning of the accident. The purpose of the flight was to practice maneuvers, and touch-and-go takeoffs and landings. According to the CFI's written statement, on the third touch-and-go takeoff the student's door popped open shortly before reaching the departure end of the runway. She noted the airspeed was 65 knots. The student retarded the throttles and engaged the brakes to abort the takeoff. The CFI stated that due to insufficient airspeed and runway, she was unable to reverse the student's decision to abort the takeoff. She then assisted with directional control and braking. The student's written statement indicated that there were no problems noted with the first two landings. However, he did note that each time the airplane accelerated it was "slow in building speed." On the third landing, the student stated that the airplane landed hard and bounced. He retracted the flaps, and applied full power. The student noted that the airspeed was slow to build and that the "airspeed indicator seemed stuck at 60 but then jumped to 71 [knots]." As the student started to apply back pressure for takeoff, his door popped open. He immediately "cut" the power to idle and engaged the brakes. The student reported about halfway from the runway to the dirt he felt his CFI "stomp" on the brakes and try to maneuver them around the turn to taxiway A1. The student felt they were going to fast to make the turn and turned the airplane back to a straight heading. Once the airplane stopped they shut everything down and exited the airplane. ## Aircraft - Registration: [N6627U](https://openairdocs.org/deregistered/N6627U-2018-07-12), registration cancelled 2018-07-12, S/N ME-214, built 1979 (OpenAirDocs) - Reported make and model: Beech BE76 - Registry model: [Beech 76](https://openairdocs.org/model/beech-76) (registry code 1153005) (OpenAirDocs) - Registry engine: [Amateur-built UNKNOWN ENG](https://openairdocs.org/engine/amateur-built-unknown-eng) (registry code 99999) (OpenAirDocs) - Category: Airplane - Serial number: ME214 - Engines: Lycoming LO-360-A1G6D 180 horsepower reciprocating; Lycoming O-360-A1G6D 180 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Registered owner: Embry-Riddle Aeronautical University - Airworthiness certificate: Standard, Normal - Last inspection: Continuous airworthiness, June 12, 2002, 3.3 hours before - Departed: PRC, PRESCOTT, AZ - Destination: PRC, PRESCOTT, AZ - Flight plan: Company VFR - Airport: PRC, Ernest A.
